damage to the o-ring.
-
Ensure that the sealing surface of the taking part is perfectly smooth and clean.
(RZ 3.2)
-
Screw the device into the corresponding thread by hand.
-
Devices with a spanner flat have to be tightened with an open-end wrench (wrench
size of steel: G1/2": approx. 10 Nm).
-
The indicated tightening torques must not be exceeded!
4.3 for NPT connectors
-
Additional seal materials, e.g. PTFE tape, may be used to provide sealing.
-
Screw the device into the mounting thread by hand.

Then tighten it with the open-end wrench (for 1/4" NPT: approx. 30 Nm; for 1/2"
NPT: approx. 70 Nm).

The specified tightening torques must not be exceeded!
4.4 Orientation of the display module
The display can be rotated in 90-degree steps, thus guaranteeing easy readability even in
unusual installation locations. In order to change its position, proceed as follows:
-
Unscrew the housing cover by hand.
-
Completely unscrew the two cross-head screws on the front side of the display
module. Pull the display module forwards and off, rotate it through 90°, 180° or
270°, and carefully plug it back on again. Reattach the display module with the two
screws.
-
Before screwing the cover back on, be sure to check the O-rings and sealing sur-
faces on the housing for damage and replace them if necessary!
-
Then screw the cover on by hand, and make certain that the housing is tightly
sealed again.
DANGER
Make sure that no moisture can penetrate into the device! The seals and sealing
surfaces must not get dirty; this is because any contamination may, depending on
the particular application or location, lead to a reduction in the level of protection
and hence to failure of the device or irreparable damage to the device!
Danger of death from explosion
Align the display module immediately on
